Asymmetric control limits for small samples
(Springer, 2009)
When designing control charts, it is usually assumed that the measurement in the subgroups are normally distributed. The assumption of normality implies that the control limits for a chart for sample averages will be ...
Combining some biased estimation methods with least trimmed squares regression and its application [Combinación de algunos métodos de estimación sesgados con regression de mínimos cuadrados recortados y su aplicación]
(Universidad Nacional de Colombia, 2015)
In the case of multicollinearity and outliers in regression analysis, the researchers are encouraged to deal with two problems simultaneously. Biased methods based on robust estimators are useful for estimating the regression ...
Estimation of clearness index model via CRS, TPRS and mars
(2011)
Nonparametric approach is more flexible than parametric approach in assuming that f belongs to a smooth family of functions. Hence, a nonparametric approach does not require an assumption of linearity. Based on our motivating ...
Comparison of the results of factorial experiments, fractional factorial experiments, regression trees and MARS for fuel consumption data
(2010)
In this study effects that are significant on the fuel consumption of F-4 aircrafts are analyzed by using different statistical methods and the results of those different methods are compared. The response variable of every ...
The individuals control charts for burr distributed and Weibull distributed data
(2006)
Constructing the control limits supposes the assumption of the normality. However, there are numerous studies on the control charts when the underlying distribution is non-normal. Several authors have investigated the ...
The individuals control chart in case of non-normality
(2006)
This article examines the effects of non-normality as measured by skewness and provides an alternative method of designing individuals control chart with non-normal distributions. A skewness correction method for constructing ...
Robust ridge and robust Liu estimator for regression based on the LTS estimator
(Taylor & Francis LTD, 2013)
In the multiple linear regression analysis, the ridge regression estimator and the Liu estimator are often used to address multicollinearity. Besides multicollinearity, outliers are also a problem in the multiple linear ...
Estimation of Clearness Index Model Via Crs, Tprs and Mars
(Isoss Publ, 2011)
Nonparametric approach is more flexible than parametric approach in assuming that f belongs to a smooth family of functions. Hence, a nonparametric approach does not require an assumption of linearity. Based on our motivating ...
The Relationship Between Parental Defense Intensity and Nest Site Characteristics in Eurasian Magpie (Pica Pica L.) - an Assessment With the Classification Methods
(Corvinus University Budapest, 2017)
Nest defense behavior varies among species and depends on different factors. However little is known of the influence of urbanization and nest characteristics on the nest defense intensity as parental investment of the ...
Using multivariate adaptive regression splines to estimate pollution in soil
(Inst Advanced Science Extension, 2017)
Heavy metal pollution is one of the main factors of the traffic pollution. The public authorities have been monitoring the concentration of heavy metal by means of sampling stations. This paper describes the response surface ...
